[0038] Example 1

[0039] Combine Figures 1 to 3The present application provides an atomizer assembly. The atomizer assembly includes an atomizer housing 100, an atomizer core assembly 200, and an atomizer base 300. The atomizer housing 100 has a liquid storage chamber 110 and an atomizer channel 120 that are connected to each other. The atomizer channel 120 has a mounting port 121 and an air outlet 122 formed at opposite ends. The atomizer core assembly 200 is mounted on the atomizer channel 120 and extends out of the mounting port 121. The side wall of the atomizer core assembly 200 has an air inlet 201, which is located outside the atomizer channel 120. The atomizer base 300 is installed on the atomizer housing 100. The atomizer base 300 has a receiving through hole 310. The receiving through hole 310 is used to receive the atomizer core assembly 200 exposed to the atomization channel 120. The hole wall of the receiving through hole 310 is provided with multiple air inlet grooves 320. An air inlet hole 321 is formed between each air inlet groove 320 and the outer wall of the atomizer core assembly 200.

[0040] In this embodiment, the gas enters the atomizing channel 120 in sequence through the multiple air inlet holes 321 and the air inlet port 201 to achieve air intake. The air inlet holes 321 are surrounded by the air inlet groove 320 and the outer wall of the atomizing core assembly 200, avoiding the need to process a complex air intake structure on a single component, simplifying the processing technology and reducing the processing cost. The multiple air inlet holes 321 improve the uniformity of air intake, thereby making the air intake smoother and the airflow softer.

[0041] In addition, compared to one air inlet hole 321, the atomization assembly provided in the present application has multiple air inlet holes 321. By increasing the number of air inlet holes 321, the air inlet area is increased, the suction resistance is reduced, and the airflow is further facilitated to flow smoothly along the atomization channel 120.

[0042] In some embodiments, combined Figure 1 and Figure 4 The number of the air inlet grooves 320 is 4 to 18. The 4 to 18 air inlet grooves 320 correspondingly form 4 to 18 air inlet holes 321, ensuring that the gas enters the atomization channel 120 at a moderate speed and pressure, thereby preventing insufficient atomization due to insufficient air intake and increasing the risk of leakage due to an excessive number of air inlet holes 321.

[0043] In some embodiments, combined Figure 1 and Figure 4 The multiple air inlet grooves 320 are spaced around the atomizing core assembly 200 to improve the uniformity of air intake, help the gas to enter the atomizing core assembly 200 from multiple directions, reduce the vortex and dead corners of the air flow in the atomizing channel 120, and improve the uniformity and efficiency of atomization.

[0044] In some embodiments, combined Figure 1 and Figure 4Multiple air inlet slots 320, or evenly distributed air inlet holes 321, surround the atomizer core assembly 200, further ensuring uniform air intake. This gentle airflow easily removes aerosol from the atomization channel 120, reducing condensation accumulation and resulting in finer and more evenly distributed aerosol particles, improving overall atomization quality. The even distribution of air inlet holes 321 ensures that airflow resistance remains stable after the airflow control valve is opened and closed, ensuring stable draw resistance.

[0045] In some embodiments, combined Figure 1 and Figure 4 The air inlet groove 320 runs through the end of the atomizing base 300 away from the atomizing channel 120 along the length direction. Based on this, on the one hand, the air inlet groove 320 is set to be through, so that the external air can enter the air inlet groove 320 more unobstructed, reducing the flow resistance and improving the smoothness of the airflow. On the other hand, compared with the air flow entering the atomizing assembly from the side of the atomizing housing 100, the air flow air inlet hole 321 is located at the bottom, which can more effectively take away the heat and aerosol generated during the atomization process, reducing the accumulation of condensate in the atomizing core assembly 200 and the atomizing channel 120. At the same time, air can enter the atomizing channel 120 evenly from all directions, avoiding the problem of uneven air intake caused by side air intake, making the aerosol more delicate and evenly distributed.

[0046] In some embodiments, combined Figure 5 and Figure 6 The air inlet 201 is arranged at a central angle of 30° to 150° relative to the atomizer core assembly 200. The air inlet 201 is distributed within the central angle range of 30° to 150° to ensure that the airflow can more evenly cover the surface of the atomizer core assembly 200 and ensure that the air inlet 201 has a sufficient air intake angle, which is conducive to increasing the gas flow area.

[0047] In some embodiments, combined Figure 2 and Figure 5 The number of the air inlets 201 is more than two, and the more than two air inlets 201 are spaced apart around the atomizing core assembly 200 to ensure that air enters the atomizing channel 120 evenly from at least two directions, which is beneficial to improving the uniformity of air intake and reducing the inhalation resistance.

[0048] In some embodiments, combined Figure 3 and Figure 5The atomizer core assembly 200 includes a support tube 210 and an end cap 220. The support tube 210 is mounted on the mounting port 121. The end of the support tube 210 away from the atomizing channel 120 is sequentially provided with an air inlet 201 and a sleeved end cap 220. The end cap 220 abuts against the wall of the accommodating through hole 310, that is, the air inlet 201 and the air inlet hole 321 are spaced apart along the length of the atomizing channel 120. External airflow can sequentially pass through the air inlet hole 321 and the air inlet 201 along the length, reducing gas return, shortening the flow path of the airflow, and reducing gas flow resistance.

[0049] Specifically, the sleeve connection between the end cap 220 and the support tube 210 increases the stability of the assembly, preventing loosening or falling off due to vibration or external forces during use, thereby contributing to the stable operation of the atomizer assembly and the continuous stability of the atomization effect. Specifically, the end cap 220 can tightly seal the end of the support tube 210, preventing the atomized liquid from leaking during the non-atomizing process.

[0050] In one embodiment, the combination Figure 3 and Figure 6 The end cap 220 includes a first end plate 221 and a first side plate 222. The first side plate 222 surrounds and is connected to the outer periphery of the first end plate 221. The first side plate 222 abuts against the notch of the air inlet groove 320. The end cap 220 is provided with the first side plate 222. The design of the first side plate 222 can increase the abutment area between the end cap 220 and the accommodating through hole 310. On the one hand, it strengthens the bonding force between the atomizer core assembly 200 and the atomizer base 300. On the other hand, it helps the end cap 220 better seal the notch of the air inlet groove 320, thereby guiding the airflow to enter the interior of the atomizer assembly along the air inlet hole 321 in an orderly manner, improving the control of the airflow and preventing the leakage of the atomized liquid.

[0051] In one embodiment, the combination Figure 3 、 Figure 4 and Figure 6 The length of the air inlet groove 320 is greater than the height of the first side plate 222. The first side plate 222 does not completely cover the notch of the air inlet groove 320. Part of the notch of the air inlet groove 320 fits together with the first side plate 222 to form an air inlet hole 321. Part of the notch of the air inlet groove 320 is exposed from the first side plate 222, which is beneficial for the airflow to leave the air inlet groove 320 and enter the interior of the atomizer assembly, thereby reducing the resistance of the airflow.

[0052] In one embodiment, the combination Figure 3 、 Figure 4 and Figure 6The first side plate 222 and the air inlet 201 are spaced apart along the length of the air inlet slot 320. Since the first side plate 222 and the air inlet slot 320 form the air inlet holes 321, that is, the air inlet holes 321 and the air inlet 201 are spaced apart along the length of the air inlet slot 320. As a result, external airflow first enters the atomizer assembly through the air inlet holes 321, and then enters the air inlet 201 at the same height as the air inlet 201. This shortens the air intake path, reduces air intake resistance, and reduces airflow turbulence during the intake process.

[0053] In one embodiment, the combination Figure 5 and Figure 6 , the outer wall of the first side plate 222 is provided with at least one clamping strip 223. The clamping strip 223 is clamped on the inner side wall of the accommodating through hole 310. On the one hand, it can increase the connection strength between the first side plate 222 and the accommodating through hole 310, thereby improving the stability of the entire atomizer assembly; on the other hand, the close fit between the clamping strip 223 and the inner side wall of the accommodating through hole 310 helps to form an effective sealing structure, which can prevent air leakage and condensate accumulation, and ensure that the air flow inside the atomizer is stable and efficient; on the third hand, it simplifies the assembly of the atomizer base 300. Under the action of thrust, the atomizer base 300 is squeezed between the atomizer housing 100 and the first side plate 222, and is fixed by means of the clamping strip 223, without the need for additional welding, bonding, hot melt connection or fastener connection.

[0054] In one embodiment, the combination Figure 3 and Figure 6 The end cap 220 further includes a second side plate 224, which is connected to the first end plate 221 and is located on the inner side of the first side plate 222. A gap is formed between the second side plate 224 and the first side plate 222. A buffer chamber 225 is formed between the first side plate 222, the second side plate 224, and the first end plate 221. The buffer chamber 225 can, on the one hand, accommodate atomized liquid or condensate that accidentally leaks from the atomizing channel 120 to prevent leakage. On the other hand, it can buffer the airflow entering through the air inlet 321 in the buffer chamber 225, thereby stabilizing the air pressure and reducing airflow turbulence, thereby facilitating the smooth entry of the airflow into the air inlet 201 and the atomizing channel 120.

[0055] In some embodiments, combined Figure 5 and Figure 6 The atomizing core assembly 200 further includes a heating element 230 , which is installed in the atomizing channel 120 . The heating element 230 generates heat to atomize the atomizing liquid in the atomizing channel 120 and mixes the atomizing liquid with the airflow to form an aerosol.

[0056] In one embodiment, combined Figure 5 and Figure 6The sidewall of the atomizing channel 120 has a through-flowing liquid outlet, which connects the liquid storage chamber 110 and the atomizing channel 120. The atomizing core assembly 200 also includes a first liquid guide 240. The heating element 230 is installed inside the first liquid guide 240. The first liquid guide 240 is installed in the atomizing channel 120, sealing the liquid outlet of the atomizing channel 120 and guiding the atomized liquid to flow stably to the heating element 230.

[0057] Specifically, the support tube body 210 has a liquid inlet 211 , and the first liquid guiding member 240 is sleeved on the support tube body 210 .

[0058] In one embodiment, combined Figure 5 and Figure 6 The atomizer core assembly 200 further includes a second liquid guide 250, which is mounted inside the first liquid guide 240. The heating element 230 is also mounted inside the second liquid guide 250. The second liquid guide 250 further buffers and stabilizes the atomized liquid. Specifically, the second liquid guide 250 is mounted inside the support tube 210 and seals the liquid inlet 211.

[0059] In some embodiments, combined Figure 1 The atomizing housing 100 has a through liquid injection port, and the atomizing assembly further includes a liquid injection plug 130 detachably mounted on the liquid injection port so as to inject atomized liquid into the liquid storage chamber 110, thereby increasing the number of times the atomizing assembly can be used.

[0060] In some embodiments, combined Figure 2 and Figure 3 The atomizing assembly further includes a sealing sleeve 400 . The sealing sleeve 400 is sealed between the cavity wall of the liquid storage cavity 110 and the outer wall of the atomizing channel 120 to prevent the atomized liquid from leaking out of the liquid storage cavity 110 .

[0061] Specifically, the sealing sleeve 400 is connected to the atomizing base 300 , thereby enhancing the integrity of the atomizing assembly, improving the rigidity of the sealing sleeve 400 , and preventing deformation.

[0062] In some embodiments, combined Figure 2 and Figure 3 The atomizer base 300 includes a second end plate 330 and a third side plate 340, and the third side plate 340 is connected and arranged around the second end plate 330. The third side plate 340 surrounds the accommodating through hole 310. The inner wall of the third side plate 340 has an air inlet groove 320. The second end plate 330 has a through hole for the atomizer core assembly 200 to pass through. The second end plate 330 enhances the connection strength with the atomizer core assembly 200 and improves the integrity of the atomizer assembly. The second end plate 330 is located at one end of the air inlet groove 320, blocking the air inlet groove 320 from continuing to extend and controlling the direction of gas flow.

[0063] Specifically, the atomizer base 300 includes a mounting plate 350, which is connected to the side of the second end plate 330 away from the third side plate 340. The mounting plate 350 is used to connect to the sealing sleeve 400, enhance the connection strength with the sealing sleeve 400, and prevent deformation of the sealing sleeve. The tight connection between the mounting plate 350 and the sealing sleeve 400 can effectively prevent the sealing sleeve 400 from falling off or loosening due to external forces during use.

[0064] In some embodiments, combined Figure 3 and Figure 4 One of the atomizer base 300 and the atomizer housing 100 is provided with a clamping block 341, and the other is provided with a clamping hole 111, and the two are snap-fitted together, making assembly simple. It is understood that in other embodiments, the atomizer base 300 can also be installed on the atomizer housing 100 by welding, bonding, hot melt connection, or fastener connection.

[0065] Specifically, the atomizing base 300 is provided with a clamping block 341 , and the atomizing housing 100 has a through clamping hole 111 . Optionally, the third side plate 340 is provided with the clamping block 341 .

[0066] In some embodiments, combined Figure 3 and Figure 4 One of the atomizing base 300 and the atomizing housing 100 is provided with a guide block 342 , and the other is provided with a guide groove, which facilitates accurate positioning and assembly of the two.

[0067] Specifically, the atomizing base 300 is provided with a guide block 342 , and the atomizing housing 100 has a guide groove. Optionally, the third side plate 340 is provided with the guide block 342 .

[0068] Example 2

[0069] The present application provides an aerosol generating device, comprising a power supply component and any one of the above-mentioned atomization components, wherein the power supply component is installed in the atomization housing 100 and is electrically connected to the atomization core component 200 to supply power to the atomization core component 200 .

[0070] The atomizing assembly has an atomizing channel 120 and an atomizing core located in the atomizing channel 120. The atomizing assembly is provided with an atomizing electrode electrically connected to the atomizing core, and the power supply assembly is provided with a power supply electrode. The power supply electrode can contact the atomizing electrode to power the atomizing assembly through the power supply assembly, ensuring that the atomizing core is heated to heat the atomizing liquid to produce an aerosol.

[0071] The aerosol generating device has an air intake channel connected to the atomizing channel 120. The external airflow enters the atomizing channel 120 along the air intake channel and carries away the aerosol generated in the atomizing channel 120. In order to prevent the aerosol from condensing during the process of being discharged from the atomizing channel 120 with the intake air flow, the atomizing core needs to heat the intake air flow while heating the atomizing liquid to increase the temperature of the intake air flow, which results in higher energy consumption of the atomizing core.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
